Google Tasks Automation via Rube MCP

Create, manage, organize, and bulk-operate on Google Tasks and task lists using Rube MCP (Composio).

Toolkit docs: composio.dev/toolkits/googletasks

Prerequisites

• Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
• Active connection via RUBE_MANAGE_CONNECTIONS with toolkit googletasks
• Always call RUBE_SEARCH_TOOLS first to get current tool schemas

Setup

Get Rube MCP: Add https://rube.app/mcp as an MCP server in your client configuration. No API keys needed — just add the endpoint and it works.

1. Verify Rube MCP is available by confirming RUBE_SEARCH_TOOLS responds
2. Call RUBE_MANAGE_CONNECTIONS with toolkit googletasks
3. If connection is not ACTIVE, follow the returned auth link to complete setup
4. Confirm connection status shows ACTIVE before running any workflows

Core Workflows

1. List All Task Lists

Use GOOGLETASKS_LIST_TASK_LISTS to fetch all available task lists for the authenticated user.

Tool: GOOGLETASKS_LIST_TASK_LISTS
Parameters:
  - maxResults: Maximum task lists to return
  - pageToken: Pagination token for next page

2. Create a New Task

Use GOOGLETASKS_INSERT_TASK to add a new task to a specific task list.

Tool: GOOGLETASKS_INSERT_TASK
Parameters:
  - tasklist_id (required): ID of the target task list
  - title (required): Task title
  - notes: Task description/notes
  - due: Due date in RFC3339 format (e.g., "2025-01-20T00:00:00.000Z")
  - status: "needsAction" or "completed"
  - task_parent: Parent task ID (to create subtask)
  - task_previous: Previous task ID (for ordering)

3. List All Tasks Across Lists

Use GOOGLETASKS_LIST_ALL_TASKS to fetch tasks across all task lists with optional filters.

Tool: GOOGLETASKS_LIST_ALL_TASKS
Parameters:
  - max_tasks_total: Maximum total tasks to return
  - showCompleted: Include completed tasks
  - showDeleted: Include deleted tasks
  - showHidden: Include hidden tasks
  - dueMin / dueMax: Filter by due date range
  - completedMin / completedMax: Filter by completion date
  - updatedMin: Filter by last update time
  - showAssigned: Include assigned tasks

4. Update an Existing Task

Use GOOGLETASKS_UPDATE_TASK to modify a task's title, notes, due date, or status.

Tool: GOOGLETASKS_UPDATE_TASK
Parameters:
  - tasklist_id (required): Task list ID
  - task_id (required): Task ID to update
  - title: New title
  - notes: Updated notes
  - due: New due date (RFC3339)
  - status: "needsAction" or "completed"

5. Bulk Insert Tasks

Use GOOGLETASKS_BULK_INSERT_TASKS to create multiple tasks at once in a single operation.

Tool: GOOGLETASKS_BULK_INSERT_TASKS
Parameters:
  - tasklist_id (required): Target task list ID
  - tasks (required): Array of task objects (each with title, notes, due, status)
  - batch_size: Number of tasks per batch request

6. Delete or Clear Tasks

Use GOOGLETASKS_DELETE_TASK to remove a specific task, or GOOGLETASKS_CLEAR_TASKS to permanently remove all completed tasks from a list.

Tool: GOOGLETASKS_DELETE_TASK
Parameters:
  - tasklist_id (required): Task list ID
  - task_id (required): Task ID to delete

Tool: GOOGLETASKS_CLEAR_TASKS
Parameters:
  - tasklist (required): Task list ID to clear completed tasks from

Common Patterns

• Get task list ID first: Always start with GOOGLETASKS_LIST_TASK_LISTS to discover available task lists and their IDs before creating or listing tasks.
• List then update: Use GOOGLETASKS_LIST_ALL_TASKS or GOOGLETASKS_LIST_TASKS to find task IDs, then use GOOGLETASKS_UPDATE_TASK to modify them.
• Mark complete: Update a task with status: "completed" using GOOGLETASKS_UPDATE_TASK.
• Create subtasks: Use GOOGLETASKS_INSERT_TASK with the task_parent parameter set to the parent task's ID.
• Reorder tasks: Use GOOGLETASKS_MOVE_TASK to change a task's position within its list or reparent it.
• Batch creation: Use GOOGLETASKS_BULK_INSERT_TASKS for creating many tasks at once (e.g., importing from another system).

Known Pitfalls

• Both tasklist_id and task_id are required for GOOGLETASKS_UPDATE_TASK, GOOGLETASKS_DELETE_TASK, and GOOGLETASKS_GET_TASK. You cannot operate on a task without knowing which list it belongs to.
• All date/time strings must be in RFC3339 format (e.g., 2025-01-20T00:00:00.000Z). Other formats will be rejected.
• GOOGLETASKS_CLEAR_TASKS permanently deletes all completed tasks from a list. This action is irreversible.
• GOOGLETASKS_LIST_ALL_TASKS fetches across all lists but results may be paginated -- check for pagination tokens.
• Task list IDs are not the same as task list names. Always resolve names to IDs using GOOGLETASKS_LIST_TASK_LISTS.
• The default task list is typically named "My Tasks" but its ID is an opaque string, not "default" or "primary".
